LU-12511 build: include firewalld files for native Linux client

Build rpms for the native Linux client fails due to xml files for
firewalld not being packaged. These files are useful for the
native client support so package them in that case.

Test-Parameters: trivial
Fixes: 9cb4b10c87d2 ("LU-14224 misc: add firewalld service configuration")
